Sending, receiving, and organizing email in Outlook.com
Hello Lynn Moore, thanks for posting this in our community.
To enable auto-sync, go to Send/Receive Settings by navigating to File > Options > Advanced > Send/Receive Groups. Set a schedule for automatic send/receive every few minutes, for example, 10 minutes. Make sure the option “Include this group in send/receive (F9)” is checked.
Outlook treats all accounts (IMAP, POP, Exchange) the same for export purposes. The export process creates a .pst file from the data stored in Outlook, regardless of whether the original mailbox is on Microsoft 365, Xfinity, or another provider. You can find more details in this article, Back up your Outlook email.
Kind regards,
John Oli
